System and method for encoding and decoding video

Abstract

Data values are encoded by mapping multi-dimensional parameters of the data values to respective parameters having fewer dimensions and creating a table of encoded data values in which the data values are represented by their respective encoded counterparts and in which redundancies between the encoded data values are reduced; and transmitting the table of encoded data values. Additionally, a set of reference data values may be transmitted for use by a decoder when decoding the table of encoded data values. The data values may be scaled prior to creating the table of encoded data values.

Description

Benefits of technology

[0012] A method for encoding and decoding video comprises receiving the video as a plurality of pixel value sets, wherein each pixel value set of the plurality of pixel value sets represents a digitized pixel of the video. Data values are encoded by mapping multi-dimensional parameters of the data values to respective parameters having fewer dimensions and creating a table of encoded data values in which the data values are represented by their respective encoded counterparts and in which

Problems solved by technology

Most user interface device Internet connections are made by relatively low-bandwidth communication channels, mainly twisted pair telephone lines, due to the existing infrastructure of such telephone lines and the cost of implementing high-bandwidth infrastructure.

However these techniques still do not provide adequate results for the low-bandwidth connections such as dial-up connections or wireless device networks (e.g., GSM or CDMA) that have data transmissions rates as low as 9.6 kilobits / sec, 14.4 kilobits / sec, 28.8 kilobits / sec, or 56 kilobits / sec.

For users at the end of a dial-up connection or wireless network, high quality video takes extraordinary amounts of time to download.

Streaming high quality video is nearly impossible, (in terms of acceptable time limits for such actions) and providing live video feeds is very challenging.
